Municipal wastewater treatment plants typically consume significant amounts of energy. To reduce this cost, it helps to save electrical energy in the right places. Sludge digestion and associated biogas recovery also play a crucial role in lowering the cost of electricity.
Sewage sludge is the only available on-site energy source in a sewage treatment plant. How efficient this can be used depends on the quality of the combined heat and power plants. Combined heat and power plants utilise the digester gas formed in the sludge digestion and convert it to electricity and heat.
We have planned, installed and commissioned numerous CHP plants from approximately 50 kWel to about 4 MWel/unit, with gas processing. We are very familiar with the optimised use of accumulated heat with different temperature levels.
